Schedule 40 fittings are used in the condensate drain line on residential and commercial air conditioning, primarily in 1/2" and 3/4" sizes. The wide availability of Schedule 40 fittings has made them the most economical choice for HVAC applications. Schedule 40 fittings are designed to handle higher pressures than DWV fittings because they can be used in commercial irrigation and potable water supply lines. HVAC applications do not require a high pressure rating, however; DWV fittings are not available in the smaller sizes required for these applications.
